So: how would you go about making a Chromebook-like laptop? Yes, I could just install any Linux distro, and then restrain myself from installing most apps other than a browser and a few utilities, but that's not quite the same; ChromeOS is nicely polished, and very pared down; it also seems to do well with low-memory systems (lots of the current models have just 2GB, which brings many Linux distros to a disk-swapping crawl), and starts up nicely quick.
It looks like the most "authentic" thing would be to dive into building Chromium OS (which looks like a fun hobby), but I'd like to find something more like Cr OS — only Cr OS hasn't been updated in quite a while. Perhaps some other browser-centric pared-down Linux would work as well. How would you build a system? And should I go ahead and order some low-end 16GB SSDs, which I now see from online vendors for less than $25?
